- Subject: [docbook-apps] Problem with MathML entities in PDF
Hi all,
I'm trying to use some of MathML entities in my DocBook files. I managed
to have aliases for such entities recognized by using the following
DOCTYPE declaration:
<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook V4.3//EN"
"file:///C:/Programmi/Xml/DTDs/docbook43/docbookx.dtd" [
<!ENTITY % ent-mmlalias PUBLIC "-//W3C//ENTITIES Aliases for MathML
2.0//EN" "C:/Java/Xml/DTDs/mathml2/mathml/mmlalias.ent" >
%ent-mmlalias;
]>
but, when I try to transform the DocBook + MathML entities markup to
XSL-FO then to PDF I keep seeing other symbols (i.e. '#') in places
where "fancy" MathML symbols should appear (e.g. the ⋂
symbol, the ∅ symbol). Has this something to do with fontsets
used by FOP, which seem to be unable to recognize and display certain
unicode characters? Is there a workaround so that I can obtain
mathematical symbols in PDF output format? (When using XHTML as the
output format, everything works like a charm.)
Best Regards,
Giulio Piancastelli.
